I was partially quoting another game I used to play on SC2 called Kobolds which is like a PVP version of this map without the random wolf and sometimes randomly at night in reference to GoT that message is shown before the map starts to spawn undead ghouls everywhere that kill off many of the weak and unprepared villagers.

We've wanted to allow Ghouls to get stronger the longer they survive. The big pain in the ass to this is that we've been unable to determine why ghouls have been disappearing randomly. Might rework the day/night cycle mechanic as a last resort
